'INsULA'roR-iBRAoKET.

Application filed January 21,1915. Seria1No.3,588.

To all whom'it may concern: f 1 e Be it known that I, FRANK .P. Konnn'r,a citizen of the United States, and residing at Milldale,in the countyof Hartford and State of Connecticut, have invented certain new anduseful Improvements in Insulator- Brackets, of which the following is aspecification, such as will enable those skilled in v the art to whichitv appertains to make and use the same.

Thls invention relates to insulatmg devices for use in connect ngtelegraph, telephone, and other electric wires with a wall, telegraphpole, or other support; and theobject thereof is to provide an improveddevice of this class which is simple in construction, comparativelyinexpensive and which may be easily employed wherever devices of thisclass are required.

The invention is fully disclosed in the following specification, ofwhich the accompanying drawing forms a part, in which the separate partsof my improvement are designated by suitable reference characters ineach of the views, and in which Figure lis a view showing my improvedwire support or holder in theform of a bracket and secured to a wall;Fig. 2 a cross section on the line 22 of Fig. 1; Fig. 3 a view showingthe method of connecting my improved electric wire holder to a telegraphpole or similar device. and; Fig. 4 a section on the line 44:' of Fig.3.

In the accompanying drawing I. have shown at a the wall of a building orother structure, and in the practice of my invention, I provide anelectric wire holder or bracket comprising a plate 6 having a pluralityof forwardly directed bracket arms 6 three of which are shown and eachof which is provided with an upwardly directed cupshaped member 72 inwhich is secured a threaded plug 6 on which, in practice, the ordinaryinsulator is secured and with which the wires are connected.

In connecting the arms 12 with the plate 6,

the back ofsaid plate is counter-sunk, so as to form a raised portion 6on the front sides thereof and the arms b are provided with necks Z)which are passed through apertures formed in the raised portions b andwhich are riveted at the back of the plate 6 to form'heads Z1 Betweenthe arms 6 the plate 6 is provided with longitudinal from sheet steel,and said plate is also provided in its opposite sides and adjacent tothe ends thereof with short, longitudinal side slots 6 through which arepassed pins, belts or similar devices 0 which are driven into the walland provided with nuts 0 and by means of this construction, the plate I)may be vertically adjusted on the wall Within certain limits. r

Instead of securing the plate 6 to a wall asshown in Figs. 1 and 2, itmay be secured to the cross arm (Z of a telegraph pole e, and in thisuse of the device, the plate I) is placed in a vertical. position,across the front face of the arm (Z and a U-shaped bracket f is mountedon the arm (Z and the side portions thereof are provided with threadedextensions f which are passed through the slots 6 in the plate 5 andpro- .vided with washers and nuts f which bear on the flanges b. Thisconstruction securely holds the plate in connection with the arm cl andsaid plate, or the bracket consisting of the plate I) and arms b may beadjusted vertically on the arms (1 within certain limits.

lhe plate b of my improved bracket wire are passed, and at the same timethe said plate is provided around the said apertures with raised, radialribs b which also serve to strengthen and stiffen said plate.

With this construction, the heads I) of the arms 5 are counter-sunk inback of the plate Z) and do not in any way interfere with the operationof securing said plate to a support, and while I have shown anddescribed the preferred form of my improved wire supporting bracket, myinvention is not limited to the exact details thereof, herein shown anddescribed, and changes therein and modifications thereof may be made,within the scope of the appended claims, without departing from thespirit of my invention or sacrificing its advantages.

Having fully described my invention, what I claim as new and desire tosecure by Letters Patent is 1; A bracket support for electric wires,comprising a plate provided at intervals with counter-sunk back partsand corresponding raised front parts having apertnres, and insulatorarms provided with necks which are passed back-wardly through saidapertures and which are riveted to form heads which are flush withtheback; of said plate, said plate being also provided between said armswith longitudinal slots having forwardly directed side flanges.

A bracket support for electric wires, comprising a plate provided atintervals with counter-sunk back parts and corresponding raised frontparts having apertur'es, and insulator arms provided with necks whichare passed bac'kwar'dly through said apertures and which are riveted toform h'eads which are flush with the back of said plate; said platebeing also provided between said arms with longitudinal slots having:forwardly directed side flz1nges,'and in the opposite side edge portionsand ad jacent to the ends thereof with short longitudinal slots,

3. A bracket support for electric wires, comprising a plate providedatintervals wit-h countersunk back parts and corresponding raised frontparts ha ing aper- Lures and insulator arms provided with necks whichare passed backwardly through said apertures and which are riveted toform heads which are flush with the back of said plate, said plate beingalso provided between said arms with longitudinal slots having forwardlydirected side flanges, means for securing said plate-to a support, saidmeans being provided with threaded members which are passed forwardlythrough said slots and provided with nuts and washers which bear on saidflanges.

In testimony that I claim the foregoing as my invention I have signed myname in presence of the subscribing witnesses this 14th day of January,1915.
